Will the Republican Party control the Senate after the 2026 Midterm elections?

How to read the numbers

Implied / market-implied YES

The probability of YES implied by current traded prices (mid or last). It is what participants are paying for, not a claim about real-world odds.

Estimated fair value (EFV)

A rule-based heuristic from the signal engine when a rule sets one, not a black-box forecast. Some signals only describe liquidity or spreads and may show no EFV.

Edge / gap

The difference between EFV and market-implied, in percentage points (EFV minus market for YES). Filters may use “largest gap.” This is informational only—not trading advice or guaranteed advantage.

Stance (above / below / near estimate)

Compares market-implied to EFV when both exist. Labels are not buy or sell recommendations.

Severity

How strong the rule hit is on a 1–5 scale. It reflects rule strength, not statistical confidence that the outcome will occur.

Volume

Reported trading activity for the market, for context on size and liquidity.

Change & sparklines

Movement in market-implied YES over the window labeled on the card—often 24h where data allows.

Signals

Rule-based flags from ingested public data. They are not trade recommendations.

This market will resolve according to the party that controls the Senate following the 2026 U.S. Senate elections scheduled for November 3, 2026. Senate control is defined as having more than half of the voting Senate members, or half of the voting Senate members and the Vice Presidency. If the outcome of this election is ambiguous given the above rules, this market will remain open until the Majority Leader of the US Senate is selected following the 2026 US general election, at which point it will resolve to the party the majority leader is affiliated with at the time of their election to that position. If the elected majority leader does not caucus with any listed party this market will resolve “Other”. Determination of which party controls the Senate after the 2026 US Senate elections will be based on a consensus of credible reporting, or if there is ambiguity, final federal and/or state election authority certification or other final official determination of the 2026 election results.
